Anyone who has seen him on television, attended one of his quirky slide-show presentations or just spent a few minutes talking with him knows it.

Phoenix is an expert on Southern California pop culture and everything Americana. His festive outfits, upbeat voice and genuine excitement for the offbeat just have a way of making people smile.

Those who haven’t had the pleasure will get a chance Sunday when Phoenix presents “Architecture in Los Angeles,” a slide show billed as a “fun-fueled whirlwind adventure extravaganza of SoCal’s greatest undiscovered and underrated mid-century architectural gems and jewels past and present.”

“The show primarily focuses on architecture,” Phoenix said in a phone interview. “Mid-century buildings that are still standing and that I feel are underrated, undiscovered and under appreciated.”

Phoenix has visited each of the places he’ll show and has stories to tell about them all.

“They are not just buildings, they are pieces of our rich culture and history,” he said. “These places are part of Southern California lore. It’s storytelling. It’s an adventure. I want the audience to realize that we live in a wonderland and that we have these design treasures everywhere which have been swept under the rug and ignored.”

“It’s a joyful, whimsical look at buildings,” he said. “I was born and raised in Southern California and I have a Disneyland sensibility. I want to share what I’ve found with the audience and hope they will go out and discover or rediscover this architecturally rich area in which we live.”
